Always wanted to send push notifications from an embedded device into my phone and I wanted it to be easy and free. Google have the API with no quota for free and then a friend recommended me a web hosting site that offers free small apps hosting. So with all pieces in place finally decided to put words into code. Just released an app into the play store to do just that, the app has a web component written in python and hosted in a free account at heroku.com. App has not be tested carefully but ...

Keep Your Home Safe and Snug This Summer! In our introductory Pi in the Sun blog, we promised projects that would make your summer better. Now we're delivering. Here are 2 Pi Projects that will allow you to worry less about keeping unwanted visitors and prowlers away while you hit the holiday road. 1. Let Frederick Vandenbosch show you how you can use a Pi, a Pi Camera and a PiFace Digital to build an alarm system that detects unwanted visitors, scares a ...

(Note: Click here to see XMP-2!) Introduction The XMOS startKIT from Farnell (or Newark) is a very low cost (£12 including VAT) processor platform that works well with the Raspberry Pi. Together is possible to construct robotics applications with almost no soldering required. The XMOS startKIT is a near-credit-card sized board with an XMOS chip on it with multiple ‘XMOS cores’ that can be programmed in C. XMOS technology allows things to run in parallel at ...

I Have had a raspberry pi and in that time have learnt a great deal. From nothing to lots of projects I have managed to make lots of things with my pi including a geocaching device called a cacheberry, a robot and even a wildlife cam. I always blog my projects at www.mypifi.net/blog which originally was for my geocaching and later a reminder to me how I built something. But now as more and more people discover my blog I have chosen to blog how I make stuff so others can try, hopefully if I find ...

This is a project that I embarked upon after reading Raspberry Pi Santa Catcher with Pi NoIR and PiFace CAD by Frederick Vandenbosch (fvan) who gets credit for a good majority of this write-up. I basically re-tailored it to focus on a practical problem that we face in our daily lives; especially those who have a hard time finding a parking spot at work: how can I be notified when a parking spot is vacated in a specific area of my workplace parking lot. Obviously, this is not a full-proof solutio ...

See the original Drinkmotizer video - and how it was built! (follow this link) Celebrate the winter holidays with your own drink mixing robot. Drinkmo never lets you down! The Drinkmotizer interface. But, Drinkmo is different too. I made a few changes to its operation. First, I changed out the sub 100oz/in stepper motor for a 280 oz/in alternative. I did this so that the drink platforms could blast through any obstacle. Whether it be debris, dry triple sec, or someone ...

I decided to install Tomcat on my Pi and see what the performance is like. First thing to do is make sure I have got the latest version of all my currently installed function - e.g. use command
sudo apt-get update
Step 1 - Install Java Java installation is very straightforward with the following command
sudo apt-get install oracle-java7-jdk
Once that has finished you can check that Java installed correctly with the command java -version ...
